Ayrton Senna (21 March 1960-1 May 1994) was a Brazilian racing driver who won three Formula One world championships for McLaren in 1988, 1990 and 1991, and is widely regarded as one of the greatest Formula One drivers of all time. He died in an accident while leading the 1994 San Marino Grand Prix for Williams. Senna has often been voted as the best and most influential Formula One driver of all time in various motorsport polls. He was recognised for his qualifying speed over one lap, and from 1989 until 2006 he held the record for most pole positions. He was also acclaimed for his wet weather performances, such as the 1984 Monaco Grand Prix, the 1985 Portuguese Grand Prix, and the 1993 European Grand Prix. He holds a record six victories at the Monaco Grand Prix, and is the fifth-most successful driver of all time in terms of race wins.
